Fully integrated BMC as a single chip on a server motherboard. The baseboard management controller (BMC) provides the intelligence in the IPMI architecture. It is a specialized microcontroller embedded on the motherboard of a computer – generally a server. The BMC manages the interface between system-management software and platform hardware.
Bare Machine Computing (BMC) is a computer architecture based on bare machines. In the BMC paradigm, applications run without the support of any operating system (OS) or centralized kernel i.e., no intermediary software is loaded on the bare machine prior to running applications. The applications, which are called bare machine applications or ...
The OpenBMC project is a Linux Foundation collaborative open-source project that produces an open source implementation of the baseboard management controllers (BMC) firmware stack. [ 1 ] [ 2 ] [ 3 ] OpenBMC is a Linux distribution for BMCs meant to work across heterogeneous systems that include enterprise, high-performance computing (HPC ...
The hardware is often integrated on the motherboard of the server, and the combined product is termed iDRAC, where the "i" is for integrated. When iDRAC Express is used, the software and hardware systems management functions are shared with one of the server's on-board network interfaces using a unique IP address.
That way, a common Ethernet connection becomes shared between the computer's operating system and the integrated baseboard management controller (BMC), usually by configuring the network interface controller (NIC) to perform Remote Management Control Protocol (RMCP) ports filtering, use a separate MAC address, or to use a virtual LAN . Thus ...

The ME has its own MAC and IP address for the out-of-band management interface, with direct access to the Ethernet controller; one portion of the Ethernet traffic is diverted to the ME even before reaching the host's operating system, for what support exists in various Ethernet controllers, exported and made configurable via Management ...
